Question

2. In a class of 30 students, of the students are girls. How many girls are there in the class?​

Answer 1

where g = number of girls

g / 30 = 60 / 100

60/100 as 60% and 30 as total classmates

by cross multiplying, 30*60 = 100g

30*60=1800

divide each side by 100 to isolate g

1800=100g

18=g

therefore, g, the number of girls in the class, is 18 girls.
